The “Real Housewives of New York” star's marriage is struggling after...

We’re told the twosome has been fighting a lot and that D’Agostino — who founded a printing company — is getting sick and tired of the drama. “There has been friction from the start. They got married so fast, they didn’t really know each other.” Added the source, “She’s a drama queen.”

Sources say the couple are hopeful that they can work through their issues.

Her relationship with D’Agostino got off to a bumpy start after it was revealed — shortly after they began dating in late 2015 — that he had previously dated “Real Housewives” co-stars Ramona Singer and Sonja Morgan.

Many were surprised that de Lesseps went through with the wedding after co-star Bethenny Frankel showed de Lesseps photographs of D’Agostino kissing his ex-girlfriend at the Regency Hotel on the night before their February 2016 engagement party.

She later told People, “It felt like someone ripped my heart out of my chest.” But “I’m not going to let a stupid kiss ruin the rest of my life … He screwed up. What he did was wrong. But this wasn’t premeditated. It wasn’t an affair. It was a mistake.”
